IMPROVEMENT IN APPARATUS FOR MIXING SOAPS, PAINTS, &c:.

Specification forming part of Letters Patent No. 147,412, dated Februaryl0, 1874 application Iiled January 22, 1874. I

To all whom 'it muy concern:

Beit known that I, CHARLES LEHMANN, of

' the city, county, and State of N ew York, have invented a new andImproved Apparatus for Stirring Soap, Faint, and other materials; and Ido hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawingforming part of this specification, in which drawing- Figure lrepresents a vertical central seetion of this invention in the plane wa', Fig. 2. Fig. 2 is a horizontal section of the same in the plane y y,Fig. l. Figs. 3 and 4 are detached views of dil'erent beaters.

Similar letters indicate corresponding parts.

This invention relates to apparatus for stirring soap, paint', and othermaterials, in which two sets of beaters which revolve in oppositedirections are employed. rIhe invention consists in combining with saidbeaters suitable scrapers to prevent the soap or other material fromadhering to the bottom or to the side of the vessel in which thestirring operation progresses. This vessel is supported by side ilanges,which engage with brackets secured to standards, on which also rests thestirring mechanism in such a manner that said vessel can be removed fromand readjusted under the heaters without disturbing the stirringmechanism. Vith the stirring-vessel is combined an additional vessel,which is supported in a similar 1n aimer' to said stirrin g-vesselsurrounding the latter, so that when the same is filled with hot waterthe contents of the stirringvessel are heated. With the twobeater-shafts is combined a reducing and a multiplying gear, so that thepower applied to the operation of the beaters can be readily adjusted tosuit eircumstances.

In the drawing, the letters A A designate two standards, which areconnected atI their top ends by a cross-bar, B, that forms the bearingfor the beater-shafts C D. The shaft (l is solid, and it extends throughthe hollow shaft D. On the lower end of this hollow shaft Dis firmlysecured a beater-fralne, E, which is composed of two upright bars, a a,and two or more pairs of radiating beaters, b b, the inner ends of thebeaters l bein g firmly secured to the hollow shaft D, while the innerends of the beaters b form eyes lwhich embrace the solid shaft G andturn loosely on the same. Between the beaters b b', and alternating withthe same, are the beaters c, which radiate from the solid shaft C, andare rmly secured to the same, and the beaters c are inclined in adirection opposite to the beaters b b, so that when the beater-shafts OI) are revolved in opposite directions the soap or other material to bestirred isalternately eut up and squeezed, and the mass becomesthoroughly homogeneous in a comparativelyshort time. rlhe material to bestirred is put in a tub, F, which is provided with flanges d d, that canbe made to engage with brackets c c secured to the standards A A, sothat said tub can be adjusted under the beaters and removed therefromwithout disturbing the stirring mechanism. rlhe bottoni of the tub ismade concave, and to the lowest one of the beaters c is secured ascraper, f, which is curved so as to conform to the surface of saidbottom, and which serves to prevent the material to be stirred fromadhering to the bottom. To one 'of the upright bars a of thebeater-frame E is secured a scraper, g, which prevents the soap or othermaterial from adhering to the side of the tub. One or both of theseupright bars a a may also be provided wings 7L It, which act as scrapersand serve to keep the side ofthe tub clean, and to press the materialdown toward the bottom. The form ofthe beaters b b c may be changed,according to the material to be stirred, and I have used with advantagebeaters such as shown inFig. 3 or in Fig. 4. IVhen it is desirable toheat the material during the operation of stirring I apply aheating-vessel, G, which is supported by anges h and brackets i, andwhich, when thus supported, embraces the tub F, so that if saidheating-vessel is filled with hot water the contents of the tub F can bekept at the desired temperature. The

shafts C D are geared together by a bevel-wheel,

j, and pinions 7a I, the wheelj being mounted on a horizontal shaft, m.,that has its bearings in the standards a, rising from the cross-bar B.With this bevel-wheel and the pinions k lis combined a reducing-gear,composed of pinions 7c', I', and o, the pinions 7u l being mounted onthe saine shaft with the pinions 7; Z, While the pinion ois mounted on ahorizontal shaft, p. If the driving` power is applied to the shaft m thebeaters b b c move with considerable speed; but if it is desired to turnthe beater-shaft slow or with comparatively little power, then the poweris applied to the shaft p. If the power is applied to the shaft m, thepinion ois thrown out of gear with the pinions k Z.

My apparatus is intended particularly for stirring` soap, but it can beused with advantage for stirring paint or other materials of a similarnature.

What I claim asnew, and desire to secure by Letters Patent, is1

1. In combination with the beaters Z1 b c, constructed as described, thereducing-gear lv l o and multiplying-gear k lj, substantially as setforth.

2. In combination with the beatersb b e, constructed'as described, thetub F, suspended from brackets e e, substantially as specied.

3. In combination with the beaters b b c, constructed as described, thetub F and heating-vessel G, both being applied substantially as setforth.
